In a hypothetical scenario where your country needed a new capital (and the current one was not an option), which city would you prefer?

The 2nd largest city? The historically most important city? The financial center? The most central city? The city that was the capital before the current capital?

For Germany I'd say that Hamburg (2nd largest) is too far north and München (3rd largest) too far south. Köln (4th largest) is too ugly imo. Bonn (19th largest) could qualify since it was the capital before and is sooomewhat central (although pretty far west), just like Frankfurt am Main (5th largest) which is the financial center and hosts the European Central Bank. There's not really a big or important city in the very center region of Germany. But in theory it could be a city like Eisenach which is not even in the top 100 of the largest cities.
